High frequency class E power amplifier

Proceedings First International IEEE Symposium Intelligent Systems, 2003
A monolithic RF power amplifier has been designed to provide 10 dBm output power at 1GHz to a 50 ohm load from 2.8 V supply. The amplifier has been developed first at 5 MHz and then at 1GHz. 0.8 /spl mu/m SiGe BiCMOS and 0.35 /spl mu/m Si CMOS technologies are used.

Load–Pull Wideband Class-E Amplifier

IEEE Microwave and Wireless Components Letters, 2007
A new technique to design wideband Class-E power amplifiers (PAs) based on the synthesis of specific load admittances at fundamental and harmonics is shown. This technique symplifies the design of wideband Class-E amplifiers by making it independent on any specific load network, implementation, and intrinsic transistor output capacitance COUT ...

Class-E high efficiency power amplifiers

[1992] Proceedings of the 35th Midwest Symposium on Circuits and Systems, 2003
Three switching mode power amplifiers are realized with collector (drain) efficiencies of 87%, 86% and 92% at 430 MHz/5 W, 100 MHz/12 W, and 5 MHz/62 W, respectively. These high efficiencies are achieved by the class-E technique and low insertion-loss load networks. Detailed design rules and major parameters are presented.

Electronically tunable class-E power amplifier

2001 IEEE MTT-S International Microwave Sympsoium Digest (Cat. No.01CH37157), 2002
The 20-W class-E power amplifier (PA) described here is electronically tunable from 19 to 31 MHz (ratio 1.67). This PA employs a single RF-power MOSFET and operates from 25 V. The output-tuning network employs fixed inductors and high-voltage MOSFETs for variable capacitors.

Stabilization of Class E amplifiers with a diode network

AEU - International Journal of Electronics and Communications, 2010
Abstract A three-element stabilization network consisting of diode and series resonant circuit to eliminate the instabilities seen in the Class E amplifiers for all load conditions when dc supply voltage is varied over entire dynamic power and frequency ranges, has been introduced.
